I fail to agree in so much as air traffic is far more closely monitored, from movement of aircraft to who may be boarding the planes, and who is learning to fly them. Trains may not fall out of the sky but some of the commodities carried can be used to level a major city. The fact is that total body count is not exactly the goal of the terrorist groups. If rail service is disrupted the American economy takes another HUGE blow. There are more goods moving via rail today than there has been in recent years and if a section of rail is tampered with to the point of derailment then what do you think the FRA will do? What will shippers do? What will the railroads do?
